Motorists travelling through Northland and Auckland are being urged to remain patient and be cautious during the holiday weekend.
Three people have died, 22 have been seriously injured and 125 have suffered from minor injuries in Labour weekend crashes in Auckland and Northland over the past five years, NZTA's regional director Ernst Zollner said.
Excessive speed is considered to be a factor in many of these crashes, he said.
"Statistics don't tell the story of the huge impact on family and friends when loved ones have been killed or seriously injured.
"We all have a responsibility to look after ourselves and our families, as well as others we share the road with."
